An audio-visual warning system is interconnect-
ed with the driver’s safety belt.
Every time the ignition is turned on, the gong will
sound for about 6 seconds to remind driver and
passenger to buckle up.
In addition, the gong will sound if vehicle speed ex-
ceeds 6 mph/10 km/h.
The safety belt warning lights in the instrument
panel and on-board computer will go off as soon
as the driver has buckled up.
Inertia reel retractor The combination lap/shoulder belt with inertia reel
locking mechanism adjusts automatically to your
size and movements as long as the pull on the belt
is slow.
Rapid deceleration during hard braking or a colli-
sion locks the belt. The belt will also lock when you
drive up or down a steep hill or in a sharp curve,
otherwise, the shoulder belt will not inhibit your
upper body movement. fAssume a comfortable sitting position.
The shoulder belt should always rest on your
upper body. The shoulder belt should never be
worn behind your back or under your arm.
fTo fasten, grasp belt and pull the belt in a con-
tinuous slow motion across your chest and lap.
fInsert belt tongue into buckle on inboard side
of seat. Push down until it securely locks with
an audible click. Pull the belt to check.
fPull shoulder section to make sure belt fits
snugly across the pelvis.
fBelts should fit snugly across the pelvis and
chest. Make sure there is no slack in the belt.
fTo unfasten belt, push in release button
(arrow) on buckle. Belt tongue will spring out
of buckle.
fTo release a latched belt, lean back to take the
body pressure off the belt.
fTo store lap/shoulder belt, allow the belt to re-
tract as you guide the latch to its stowed posi-
tion.

Car Audio Operation/Tips FM reception
A vehicle is not an ideal place to listen to a radio.
Because the vehicle moves, reception conditions
are constantly changing.
Buildings, terrain, signal distance and noise from
other vehicles are all working against good recep-
tion.
Some conditions affecting FM may appear to be
problems when they are not.
The following characteristics are completely nor-
mal for a given reception area, and they do not in-
dicate any problem with the radio itself.
Note
Electronic accessories should only be installed by
your authorized Porsche dealer.
Equipment which has not been tested and ap-
proved by Porsche may impair radio reception. Fading and drifting
FM range is limited to about 25 miles (40 km),
except for some high power stations.
If a vehicle is moving away from the desired sta-
tion’s transmitter, the signal will tend to fade and/
or drift. This condition is more prevalent with FM
than AM, and is often accompanied by distortion.
Fading and drifting can be minimized to a certain
degree by careful attention to fine tuning or selec-
tion of a stronger signal.
Static and fluttering
When the line-of-sight link between a transmitter
and vehicle is blocked by large buildings or moun-
tains, the radio sound may be accompanied with
static or fluttering because of the characteristic of
FM.
In a similar effect, a fluttering noise is sometimes
heard when driving along a tree-lined road.
This static and fluttering can be reduced by adjust-
ing the tone control for greater bass response un-
til the disturbance has passed. Multipath
Because of the reflecting characteristics of FM,
direct and reflected signals may reach the antenna
at the same time (multipath) and cancel each other
out.
As a vehicle moves through these electronic dead
spots, the listener may hear a momentary flutter
or loss of reception.
Station swapping
When two FM stations are close to each other, and
an electronic dead spot, such as static or multi-
path area, interrupts the original signal, some-
times the stronger second signal will be selected
automatically until the original one returns.
This swapping can also occur as you drive away
from the selected station and approach another
station of a stronger signal.

Compact disc player
Caution!
To avoid damage to compact disc player and
discs.
fUse only compact discs labeled as shown, hav-
ing no dirt, damage or warpage.
fNever attempt to disassemble or oil any part
of the player unit.
Do not insert any object other than a disc into
the slot.
Remember there are no user-serviceable parts
inside the compact disc player. fDo not allow the disc to sustain any finger-
prints, scrapes or stickers on the surfaces.
This may cause poor sound quality.
Hold the disc only on the edge or center hole.
fWhen not in use, take the disc out of the player,
put the disc back into its case and store it
away from dust, heat, damp and direct sun-
light.
Leaving the disc on the dashboard in the sun
can damage the disc.
fIf the disc gets dirty, clean the disc by wiping
the surfaces from the center to the outside in
a radial direction with a soft cloth.
Do not use a conventional record cleaner or
anti-static record preservative.
Disc cleaners are available in audio stores.
